HAY PRESS.

SPECIFICATION forming part of Letters Patent No. 584,300, dated June 8, 1897.. Application filed December 21, 1895. fierial No. 572,865. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM T. YOUNG, of

Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Hay Pressing and Baling Machines, of which the following is a specification.

My invention relates to improvements in presses for compressing and baling hay or other fibrous material; and it consists in various improvements in the manner of compressing the material in a chamber by a plunger and forcing the accumulated mass through the contracted end of the baling-chamber, I 5 novel means for contracting the end of the baling-chamber, and improvements in the manner of applying power to the plunger, whereby great power is easily obtained and rapidly applied to the plunger.

Other objects and advantages will be fully understood from the following description and claims. I accomplish these objects by means of the mechanism hereinafter described, and particularly pointed out in the claims.

Reference is had to the accompanying drawings, forming part of this specification, in which similar characters of reference are used to indicate the. same parts throughout the several views.

Fig. 3 is an outside view of one of the disk roller-standards. Fig. 4 is a sectional view through A A of Fig. 2. Fig. 4 is a similar view through the frame at the point B in Fig. 1. Fig. 4 is a similar view through the frame at the point C in Fig. 1 Fig. 5 is an elevation of the radial arm and circular track with antifriction-rollers. Fig. 6 is an elevation of sections of plunger and connecting rods. Fig. 6 is a detail view of cross-head and antifrictionrollers. Fig. 7 is an elevation of the tensionrod. Fig. 8 is a side elevation of plunger. Fig. 9 is a front elevation of plunger. Fig. 10 is a rear elevation of baling-chamber and showing tension-spring. Fig. 11 is a plan view of the wooden wedges. Fig. 11 shows a variation in the springs used in or under the wedges. Fig. 12 is a plan view of the plunger in section. Fig. 13 is an elevation of a plate for throwing tension-rod in place. Fig. 14 shows sections of the baling-chainber and the plunger and the arrangement of the wooden wedges.

The entire frame of the press isIconstructed, preferably, of steel or other metal shapes and plates. The chamber is of ordinary construction, having a hopper, follower-heads, springpressed dogs, (be. attached or bolted to the plunger in anysuit' able way, and the plunger is mounted on rollers in, which travel on the bottom of the compression-chamber. WVooden wedges n are bolted to the plunger on angle-plate n and to the front of the inside of the compression chamber. Spiral or other springs a are inserted in or under the wooden wedges to take up the shock and to prevent the rebound of the plunger. A tucker c or top plate is mounted above the plunger on suitable braces n and W. The brace n is attached to the plunger-rod, and the braces or supports 01 are attached to the bottom plate of the plunger. The plunger-rod l is connected to the plunger by means of a pin running through the angle-plates a The charge on entering the baling-chamber W is tucked by means of the top plate a of the plunger acting in connection with the depression d in the top plate of the balingchamber. The top plate 0 is bolted or hinged to the supports, so that the end F may be depressed on entering or being withdrawn from the baling-chamber. The end F has for flexible supports the springs g. By this arrangement the Wedging of the plunger in the balingchamber is avoided, and the easy withdrawal of the same and thorough tucking of charge are assured. The recoil of the charge is checked by means of retainers h, held in position by the springs 7c, the retainers being hinged to the walls of the compression-chamber and acting through slots in its side walls.

The tension of the rear of the pres-s is secured by the taper given to the baling-chamher by means of the curved steel spring Z, the screws m, and the arches 7L which force in the longitudinal bars 0 in the side of the The plunger-head N is baling-chamber and contract the vertical depth of the chamber by bringing the top and bottom plates nearer together.

The frame for supporting and guiding the plunger-rod and its connections consists of the angle-bars m m and m suitably riveted together, as shown in Figs. 4, 4:, and 4 The plunger-rod Zis attached to the connection rod 19, as shown in Fig. 6. This rod is made to act in a straight line by means of an antifriction cross-head at junction of the connecting-rod p and the plunger-rod Z. This crosshead consists of the jaw-plates o and w, the rollers 25 and u acting on a vertical pin 19, and roller 0; acting on a horizontal pin with a suitable boX. These rollers run on longitudinal bars m m and m The lower jaw W" of the cross-head has an arm "W that Works between bars m and m and rollers V one above and one below arm W, are mounted 011 this arm. These rollers revolve on a vertical pin and run against bars m and m.

The power for driving the plunger is obtained by means of a revolving disk or crank mounted on a suitable frame. To the center of the disk is bolted a boss or bearing 19 for receiving the center pin A. The power-bearing for pin A is mounted on a plate on. (Shown in Figs. 3 and 4: and in dotted lines in Fig. 1.) This plate is mounted on the frame composed of the pieces 4%, 00 and 0c, bolted to bar m the latter forming one side of the frame. This frame is braced by a piece 00 riveted to 00 and 00 and to the bar m Standards 71, are mounted on the frame at various points about the circumference of disk I). In these standards are mounted antifrictionrollers h, one above and one belowthe disk, thus securing the steady revolution of this disk. This disk can be revolved by any suitable power. To use animal power, I attach a lever B to the top of the disk b by means of straps and k The legs of strap 70 are longer than those of strap 70 and the lever is bolted to the strap 7&

' To drive the disk by steam or other power, a pulley-wheel could be mounted on the center of the disk to be operated by a band and a drive wheel, or a rack could be attached to the rim of the disk to be operated by a pinion. An annular flange 6 is riveted to the under side of disk I), and dogs E and E are riveted to this flange. A radial arm 11 is pivoted to the frame at H and to connecting-rod p and fieXion-rod p at H This radial arm travels over curved track H and a steady movement over this track is secured by the rollers H and H FleXion-rod p is pivoted at H and carries a pin 19 in the other end. This pin is operated by the dogs E and E.

The power is obtained by revolving the disk in an opposite direction to the movement of the hand of a clock by means of lever 13 When the disk is revolved, the dogs E and E alternately catch the pin 12 and force the pin along with the disk until the disk has revolved far enough to throw the pin out of the provided with an antifriction roller or ball bearing. A plate (see Fig. 13) is riveted to bar m to throw the tension-rod against the annular flange on disk I) when this is drawn back by spring H The return stroke of the plunger is effected by means of the recoil in the pressed charge and by the steel spiral tension-spr'ing H bringing the plunger back to its original position. This spring is attached to the antifriction cross-head and to the front part of the frame to pivot-pin H There are two strokes of maximum length to each revolution of the disk or crank.

It will be seen that little power will be required to operate the press and that there is almost uniform demand for power, due to variable piston speed, with uniform velocity of disk or crank, securing to the prime motor Z) rapid increase in mechanical advantage simultaneously with the increased resistance which is offered to the plunger. This variable plunger speed or mechanical advantage results from the relatively slow speed of flexionrod p as compared with that of the disk or crank as the end of the stroke is approached, and from the fact that the connecting-rod p and radial arm 11 are approaching a straight line throughout the stroke and approximate the same closely at the end of the stroke, with the result that a straight pull on the flexionrod p exerts an enormous pressure on the plunger-rod 1 when most needed, thus'equalizing the demand for power from prime motor 19.
